A wide range of responses to sublethal levels of DDT exist, many of which are species specific and vary within each species depending upon age, sex, and physiological state. Sublethal levels of DDT do cause an increase in the adrenal cortical tissue of bobwhite quail, which may cause increased secretion...

Coturnix quail (Coturnix coturnix) chicks were given sublethal amounts of chlordane, dieldrin, endrin, DDE, Ceresan M, or Aroclor 1254 (a polychlorinated biphenyl) in their feed, beginning at seven days of age, and their avoidance response to a moving silhouette was measured daily for fourteen days. The birds were on dosage...

Mourning dove (Zenaidura macroura) breast muscle samples from birds collected in 1970-71 from Rhode Island, Pennsylvania, Maryland, Missouri, Kentucky, Virginia, Arkansas, Tennessee, North Carolina, South Carolina, Mississippi, Alabama, Georgia, Louisiana, and Florida were found to contain residues of DDT, DDE, DDD, polychlorinated biphenyls, dieldrin, mirex, mercury, and heptachlor epoxide in...

Nationwide monitoring of organochlorine and mercury residues in wings of approximately 5,200 adult mallards and black (ducks bagged during the 1969-70 hunting season showed DDE, as in 1965 and 1966, to be the predominant residue. PCB's were next in overall prevalence, followed by mercury, DDT, dieldrin, DDD, and heptachlor...

Nearly all brown pelican eggs collected from 13 colonies in South Carolina, Florida, and California in 1969 and from 17 colonies in South Carolina and Florida in 1970 exhibited eggshell thinning. Of the 100 eggs analyzed for residues of pollutants, all eggs contained measurable quantities of DDE; most eggs contained...

During Late 1970 and early 1971, 229 woodcock (Philohela minor) were collected from 23 Eastern and Midwestern States. Analyses for chlorinated hydrocarbons and mercury in these migratory birds showed generally low levels which are not considered dangerous to human consumers. In this survey, Louisiana woodcock had lower...

Measurements of shell thickness of the eggs of five species were subjected to nested analyses of variance. The analyses separated variation into two or three levels for which variances and percentages of the total variation were derived. The results show that differences among measurements of the same egg contribute little...

Ability to establish and maintain self-sustaining breeding colonies of captive Red-winged Blackbirds (Agelaius phoeniceus) would facilitate long-term studies designed to develop methods for alleviating blackbird depredations as well as provide basic life history data. To be most useful, the colonies should be established in pens near laboratory facilities; this frequently...

The longevity record for a 36-year-old Herring Gull, Larus argentatus (Pettingill 1967, Auk 84: 123), is erroneous. Herring Gull with band number A-676871, the basis of the record, was found dead on 20 June 1966 on the shore of Little Traverse Bay near Petoskey, Michigan, and reported to the Bird...

The Ninety-first Stated Meeting of the American Ornithologists' Union was held 8-12 October 1973 at Provincetown, on Cape Cod, Massachusetts, under the sponsorship of the Nuttall Ornithological Club, which was celebrating its centennial year. Business, technical, and social sessions were held in the Provincetown Inn. Field trips were taken...

Examination of 58 Clapper Rail specimens taken in the breeding season from the Colorado Valley and the west coast of mainland Mexico verifies the distinctness of the races Rallus longirostris yomanensis, R. 1. rhizophorae, and R. 1. nayaritensis. Rallus 1. yumanensis is a relatively pale brown, pointed-winged, summer resident of...
